Speed of Stall Torque Motor drops as it is loaded and reaches to zero as seen from the graph. After reaching zero speed, if the shaft of Torque Motor is rotated by force in opposite direction of normal rotation then the Torque Motor tries to resist it. (Please see graph below X-axis, which shows T/ N curves at different voltages)
This means that when an energized Torque Motor is driven by an extended source against normal rotation it exerts an almost constant lacking torque on this extended source.

• One main application of these Stall Torque motors is Cable reeling drums (Motorised Cable Reeling)
• The typical property of Stall Torque Motor is used in unwinding application of cable reeling drums. Motorised Cable Reeling Drums (C.R.D.) are used to supply electrical power to moving equipment like Stackers, Reclaimers, Trippers etc. in Steel Plants, Cement Plants, Power Stations, Ports/Docks etc.
• Cable Reeling Drums are driven by Stall Torque Motors through Gear-Boxes of required ratios. Cable Reeling Drums rotate in both directions depending upon application ( i.e. whether cable is paid-off or is reeled in). We are supplying motors for cable reeling drums (Motorised Cable Reeling) as per Mark standard and also direct replacement for Demag / AKH / other Chinese manufacturers.
